[Vwdiesel] Crappy fuel? (was Touareg)

[TexasTDI]

Our higher sulphur diesel won't allow us to use the same catalytic
converters and particulate traps that Europe does.  But the main reason the
EGR and intake get clogged up is because the EGR lets in sooty exhaust into
the intake and the CCV lets in oily vapors from the motor into the intake.
Add these two together and you get a clogged intake and EGR.
